Expansion joint sealing in Shorwell

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Common problems we fix in Shorwell

Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks.

Common reasons buildings call us in:

  • Torn sealant in brick or block movement joints
  • Damp inside where a wall movement joint has failed
  • Chipped joint edges on forklift routes
  • Brittle, chalky sealant on external joints

For an estate such as Whitecroft Hospital, 3.1 miles to the north-east of Shorwell, the joints in ramps, decks and long building elevations all need attention over time.

Before you book anyone

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether primer will be used where the manufacturer specifies it
  • How the existing material will be dealt with
  • The named product and why it was chosen

Choosing a commercial sealant contractor

Expansion joint sealing for commercial buildings in Shorwell

Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on blockwork control joints, car park decks and ramps and podiums and floor movement joints, and the usual reasons a site gets in touch are damp inside where a wall movement joint has failed and water dripping through deck or ramp joints. Most enquiries from Shorwell start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For a site near Shorwell, measurements and photos up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Leave it or put it right?

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. Halls, stores and units around places like Shorwell may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Keep product details with the building records for the next reseal
  • Clear dirt from joint lines during routine cleaning
  • Inspect exposed joints once the cold weather has passed
  • Leave barriers in place until fresh joint sealant has cured

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. A routine sweep is the simplest protection.

A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Resealing early limits the damage.

Shorwell: questions and answers

Our building in Shorwell is near the coast: does that change the sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Is Shorwell off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

What exactly is a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint and both need a flexible seal.

What sealant do you use in movement joints?

Movement capability matters most, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Shorwell can form part of a wider programme across the Isle of Wight.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Shorwell may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we will be in

Expansion joint sealing in Shorwell: the local picture

With the shore within about 2 miles, Shorwell counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Shorwell is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

For floors and slabs around Shorwell, the product is chosen for the traffic and the movement at each joint.

Shorwell is about 5 miles south-west of Newport, in the Isle of Wight. Shorwell sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else.
